Diammonium fertilizer represents a key source of N and phosphorus for agricultural production.
Composition
The typical DAP bag contains 18% nitrogen, 46.0% phosphorus pentoxide and 0.0% potassium, commonly expressed as 18‑46‑0 (NPK).
Current Prices
As of 2025 the standard price for a 50 kg bag of DAP in Kenya ranges from KES 6,500 to KES 8,500, based on supplier and region.
One 1 kg pack is priced around KES 130, website providing a cost‑effective option for home garden growers.
Applications
- Allium cepa farms benefit from improved bulb development.
- Maize fields receive strong stalk growth.
- Sukuma wiki and Arachis crops show higher yield.
- Coffea arabica plantations use DAP in the early growth stage for root system vigor.
Pros
Rapid nitrogen release supports vegetative growth, while phosphorus stimulates root development and flower initiation. The water‑soluble nature allows easy integration with irrigation systems.
Limitations
Over‑application can lead in soil alkalinity increase, possibly affecting acid‑loving crops. Incorrect timing may cause nutrient leaching during heavy rains.
Where to Find
Verify the HS code 210690 and batch number for genuine before purchase. Regional agro‑dealers, e‑commerce platforms, and farm supply outlets offer DAP in bag sizes ranging from 10 kg.
